The board's design is centered around the series chipset, which supports various multimedia inputs including HDMI, USB, and VGA. Its integrated power section typically converts AC input into DC voltages such as 12V and 5V to power the logic board, while a dedicated boost converter generates the high voltage required for the LED backlight strings.
